Don’t know what your budget is, but Shanon Smythe advertises reconditioned dashes on the Datsun 1200 Fan Club Facebook group. About $550 or a little less if you supply dash to recondition. I think he’s in Queensland.
Happy New Year to you. I was only watching your ute run on Youtube the other day. Good luck with the latest engine build, sounds like your still enjoying the ride.
Not sure if it will help you or confuse matters, but my coil overs on a 200b strut have a 200mm (uncompressed) length. Then there is a 50mm helper spring, to keep the main spring in place on full droop (ie when you jack it up). Coil over kit was from Techno Toy Tuning and was what they recommend for Datsun 1200.
Note: I have yet to install them so can’t really say how good or bad they are yet.
